1. בהתבסס על המשוואה הבאה של ה- תגובת היתוך, קבע את האנרגיה המופקת בתגובת ההיתוך!
פתרון
Mass of reactant and product :
מסה of מגיב (mמגיב) = 1.0078 amu + 1.0078 amu = 2.0156 amu
Mass of מוצר (mמוצר) = 2.01410 amu + 0.00055 amu = 2.01465 amu
The loss of mass in the reaction :
Δm = mמגיב - mמוצר
Δm = 2.01560 אמו - 2.01465 אמו
Δm = 0.00095 אמו
The loss of mass in the reaction is 0.00095 sma.
1 amu = 931 MeV. 0.00095 amu = 0.00095 x 931 MeV = 0.88445 MeV.
amu = atomic mass unit
MeV = megaelectron-volt (unit of energy)
2. Based on the following equation of the fusion reaction, determine the energy produced in the fusion reaction!
פתרון:
Mass of reactant and product :
מסה of מגיב (mמגיב) = 2.014 אמו + 3.016 אמו = 5.03 אמו
Mass of מוצר (mמוצר) = 4.0026 אמו + 1.0084 אמו = 5.011 אמו
The loss of mass in the reaction :
Δm = mמגיב - mמוצר
Δm = 5.03 amu – 5.011 amu
Δm = 0.019 amu
The loss of mass in the reaction is 0.019 אמו.
1 amu = 931 MeV. 0.019 amu = 0.019 x 931 MeV = 17.689 MeV = 17.69 MeV.
3. Based on the following equation of the fusion reaction, determine the energy produced in the fusion reaction!
פתרון:
Mass of reactant and product :
מסה of מגיב (mמגיב) = 13.0033 אמו + 2.0141 אמו = 15.0174 אמו
Mass of מוצר (mמוצר) = 14.0030 אמו + 1.0078 אמו = 15.0108 אמו
The loss of mass in the reaction :
Δm = mמגיב - mמוצר
Δm = 15.0174 אמו - 15.0108 אמו
Δm = 0.0066 אמו
The loss of mass in the reaction is 0.0066 amu.
1 amu = 931 MeV. 0.0066 amu = 0.0066 x 931 MeV = 6.1446 MeV.
4. Based on the following equation of the fusion reaction, determine the energy produced in the fusion reaction.
פתרון:
Mass of reactant and product :
מסה of מגיב (mמגיב) = 4 (1.0078 אמו) = 4.0312 אמו
Mass of מוצר (mמוצר) = 4.0026 אמו + 0.0005 אמו = 4.0031 אמו
The loss of mass in the reaction :
Δm = mמגיב - mמוצר
Δm = 4.0312 אמו - 4.0031 אמו
Δm = 0.0281 אמו
The loss of mass in the reaction is 0.0281 amu.
1 amu = 931 MeV. 0.0281 amu = 0.0281 x 931 MeV = 26.1611 MeV.
